In OBIEE 11g there is no link on the homepage for “Oracle Answers” like there was in the 10g version. Where is it or how to get it to appear?

Solution

BIEE 11g has been re-engineered in 11g, especially with the inclusion of WebLogic in the mid tier. A new look and feel is displayed from the 10g version. Now when connecting in 11g BIEE, you basically see Answers.

On the main 11g page, some of the latest Dashboards and Reports that have been created are displayed, plus there are still links to create a new report or open another dashboard.

So it is more a look and feel (cosmetic) change than anything else as the same functionality exists in both versions.

Symptoms
In OBIEE Presentation Server log, you may see the following warning messages:

Customers did not run catalog upgrade from the previous 11g version to the current version. Therefore, we have to upgrade it at run time in memory without saving it (if the catalog is upgraded through upgrade process, it will be upgraded and saved permanently in the catalog.) We give this warning message to warn customers that it is recommended to perform the catalog upgrade otherwise the application will need to perform the upgrade in memory.

Solution
The resolution for the issue has been documented. It is suggested to use the following:

“I need to create a prototype for the following Pivot Table. I’m putting a view as I would see in Answers.
————-|9/1/2009|9/2/2009|9/3/2009|MTD|Q1|Q2|Q3|Q4|YTD
________ |_______________________________________________
Customer |Some metric (for example Income $)

I’ve been unable to come up with a way to do this in Answers without creating additional columns (such as Income YTD, Income MTD, Income Today, Income Yesterday, etc.). Even with that, I can’t figure out what’s the best way of arranging pivot columns in Answers to create this report. Does Answers allow for mixed granularity like this in pivot?”

“The question was how to transpose various hierarchiecal levels on x-axis? Not homgenous, but different ones. For example, if I dragged columns “Year” and “Qtr” to the Columns section in Pivot I get the following:
2009
—-
q1|q2|q3|q4

What I want is to have it liks this:
2009|q1|q2|q3|q4

It seems as it’s not possible right now. But I’ll be glad if you can correct me”

Someone suggested that this wasn’t possible. Original author suggested using only tab “Measure labels” in Columns. Call appropriate metrics as Q1,Q2,Q3, etc. (use filter for them) – and use them in measures section.”

However, I thought there should be another solution. I’ve contacted metalink and was told that this wasn’t a technical, but implementation issue and as such services of Oracle Services’ were necessary.

So far, i wasn’t able to come up with anything better than using custom columns. This method isn’t ideal – since it’s very cumbersome to implement and would fail relatively easy.

Main challenge is hiding some values in Pivotal columns without affecting aggregate’s total.

Watching the server as the report runs, a large file is created in the /OracleBIData/tmp directory. Once the file hits 2GB in size, the report generates the error. It appears that we are hitting a 2GB file size limitation.

Please let me know how to resolve this issue. thank you.
Cause
We’ve researched on this error and this issue has been logged as a BUG “BUG 6998143 – ANALYTICS TEMP FILES CANNOT BE LARGER THAN 2GB “.
According to BUG 6998143, in UNIX/LINUX env tmp files over 2 GB in size lead to an error. This bug was fixed for Window env in OBIEE 10.1.3.2, and has been fixed for UNIX/LINUX env in OBIEE 10.1.3.4.

Solution

Please note that a patch for BUG 5543386 – ANALYTICS TEMP FILES CANNOT BE LARGER THAN 2GB, for Linux is now available.

While auditing our OBIEE security model We’ve stumbled into behavior that we think is a bug. If it’s not, then I hope it’s a feature that would be removed in the future. Here’s a description of how we get this particular Presentation services behavior:

1. Summary – Our goal is to be able to add new users in RPD in online mode, assign them to their respective repository security groups ( based on data-level and row-level security), and during their first loginÂ have them automatically assigned to one of 2 appopriate Presentation catalog group (that is used for presentation security, such as prohibiting overwriting of shared reports). We use OS authentication model with Impersonator (OBIEE picks up and strips users’ OS username). However, the problem doesn’t seem to be SSO-related or OS-related.

e) If we click on “Add New Member”-> “Show Users and Groups” – there’ll be a red-stop symbol (padlock image)

We’ve filed an SR with Oracle Support, and still waiting for an answer. I personally think that in future OBIEE releases – the Presentation Services should be tied closer with BI server – maybe going as far as consolidating those 2 modules.
